All living things are made up of cells. Every cell in all living things has
chromosomes. The chromosomes within the cells contain the genes. Those genes contain the instructions to determine which traits the offspring will have.
Many distinguishing characteristics or traits of the offspring of living things are inherited from their parents. Heredity is the term given for the passing of traits from parent to offspring. All living things have traits. In animals, leopards have spots, zebras have stripes, giraffes have long necks, fish have fins, insects have antennas. In plants, flowers have leaves, thorns, colors and shapes. In humans, people have hair texture, eye color, freckles and skin color. These are all examples of inherited traits. However, other traits like playing an instrument, doing gymnastics, or performing tricks, are all examples of acquired or learned traits. Acquired or learned traits do not get passed along to offspring.
Traits can also be influenced by our environment. Flamingoes are often pink which is a result of what they eat. Many Flamingoes are pink which is very similar to the color of the shrimp that they eat. Poison dart frogs are a very poisonous type of frog, it is thought that they get their poison from the insects they eat, scientists don’t think they inherit the poison.
